It's hard to find better than Apple's Magic Keyboard if you want a case that turns your tablet into an acceptable replacement for a laptop. iPads attach magnetically to it, sitting over the keys and trackpad, while allowing you to tilt it 90 to 130 degrees to get the correct viewing position. It feels surprisingly sturdy and the keyboard itself is great for using for long periods of time. It doesn't have the same stability that a standard laptop would if you use it on your lap, but you also won't feel like your setup will collapse at any point. The glass trackpad is another highlight: it's wide enough to allow gestures and is generally very easy to use, even if it's noticeably smaller than what you'd get on a full-size MacBook.
While it offers one of the best typing experiences you can get with the selection of cases for the iPad Pro and other models, the Magic Keyboard has two major drawbacks: it doesn't provide much drop protection, and it's expensive. The edges don't wrap around the iPad, so this isn't the best buy if you're particularly prone to dropping things. Additionally, the Magic Keyboard costs between $300 and $350, depending on the size of your iPad. It's certainly the most luxurious iPad case on this list, but those who want their iPad to be as functional as possible will get a lot of use out of it. If you want a cheaper, but official Apple alternative, you could consider Apple's Smart Keyboard Folio, which is priced at a more affordable $179.
